9902.09.06 - Dispersions and suspensions of approximately 20 percent by weight 1-propene, 1,1,2,3,3,3-hexafluoro-, telomer with chlorotrifluoroethene, oxidized, reduced, ethyl ester, hydrolyzed, sodium salt (CAS No. 220207-15-8) in water (provided for in subheading 3402.11.50)

This HTS classification, 9902.09.06, covers a specific chemical substance: dispersions and suspensions of a complex fluoropolymer derivative, identified by CAS No. 220207-15-8, in water. The substance is characterized by its preparation process, which involves telomerization of 1-propene and chlorotrifluoroethene, followed by oxidation, reduction, ethyl ester formation, hydrolysis, and conversion to its sodium salt. This precise chemical composition and state of dispersion are key to its classification under this temporary provision.

Unlike the vast array of primary products found in the initial chapters of the HTS (such as live animals in Chapter 01), this entry falls under Section XXII, which deals with special classification provisions, temporary legislation, and trade agreement modifications. Therefore, its distinction from sibling categories at the HTS Database Root level lies in its nature as a temporary, specific classification, likely implemented to address unique trade or regulatory circumstances rather than to categorize a broad class of goods. This contrasts sharply with foundational HTS categories that define staple commodity groups.

As HTS code 9902.09.06 is a leaf node, there are no further subcategories. This signifies that the detailed description provided is specific enough to pinpoint the exact product intended for this classification. Importations falling under this code must meet the exact chemical and physical specifications outlined, including the percentage of 1-propene and the specific derivative in a water-based dispersion, and are referenced as being provided for in subheading 3402.11.50, indicating a primary classification for surfactants that is being temporarily modified or supplemented.
